makeCrosscheckVersion.sh

#!/bin/bash

# 此脚本作用：
#    1. 将 PDF 文档分割为五部分
#         A 封面到扉页
#         B 原创声明到授权声明
#         C 摘要到参考文献
#         D 作者简介到致谢
#         E 附录
#    2. B 和 D 都通过处理使文字无法复制，得到B-rst，D-rst
#    3. 将 A，B-rst，C，D-rst，E 组合为新的 PDF 文档


# ！！！注意
# 执行此脚本需
#     1. 安装pdftk、Ghostscript并将其路径加入PATH环境变量
#           pdftk: https://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/
#           Ghostscript: https://www.ghostscript.com/download/gsdnld.html
#     2. 将TeX Live可执行文件路径加入PATH环境变量
#     3. 有类Linux环境，可执行cat、grep、awk、head等命令
#           Windows下安装Git并使用Git Bash可得到，Git: https://git-scm.com/downloads
